1 claim. 1

This invention relates to disinfectant dispensers for toilet bowls ofthe type having automatic flushing valves and also for ush tanks oftoilet bowls in which the dispensing instrumentalities are actuated bythe rise and fall of water in the toilet bowl or in a flush tankassociated therewith, and in particular this invention relates to adisinfectant container having a depending neck and with a controlchamber extended from the lower end of the neck, and the control chambermay be provided with a tube extended downwardly into a toilet bowl withthe end of the tube positioned below the normal level of water in thebowl.

The purpose of this invention is to provide a disinfectant dispenser forsupplying disinfectant to toilet bowls in which disinfectant is onlysupplied to the bowl when the bowl is flushed.

Various devices have been provided for supplying disinfectant to toiletbowls, urinals, and the like but in the usual device of this type adisinfectant is supplied continuously and a comparatively large amountof disinfectant is used. With this thought in mind this inventioncontemplates a disinfectant dispenser particularh7 adapted for toiletbowls which operate only as water is iiushed through the bowl.

The object of this invention is, therefore, to provide means forconstructing an automatic disinfectant dispenser that is operated by therise and fall of water in a bowl, tank, or container and that dispensesdisinfectant only with the rise and fall of the water.

Another object of the invention is to provide a disinfectant dispenserthat may be incorporated in flush tanks of toilet bowls or connecteddirectly in the bowls without changing the design or construction of thetank or bowl.

A further object of the invention is to provide a disinfectant containerfor toilet bowls which operates with rise and fall of water in the bowlor in a flush tank associated with the bowl which is of a simple andeconomical construction.

With these and other objects and advantages in view the inventionembodies a container having a depending neck with a control chamberbelow the lower end of the neck and with a valve member positioned tocoact with the reduced section of the neck.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawings wherein:

The gure is a view illustrating the disinfectant dispenser having thecontainer mounted on the wall and connected by a tube to a toilet bowlin 1 which the lower part of the dispenser is broken away and shown insection and in which the toilet bowl is shown in section.

Referring now to the drawings wherein like reference characters denotecorresponding parts the improved disinfectant dispenser of thisinvention includes a bottle container for the disinfectant and thecontainer is mounted on a wall 56 by a casing 5l having a tab 58 on theupper end by which the container is mounted on a wall by a nail orscrew.

The container has a neck 59 in which operates a throttle valve 6|. Theneck 59 is threaded into a lower chamber 62 on the upper end of a smalltube 63 which extends to a toilet bowl 64 and into the water thereof.When the bowl is ushed the water level drops below the end of the tubeand air will rise in the tube 63 permitting a small amount of air topass upward into the bottle 55 which relieves the vacuum so that a smallamount of the disinfectant trickles downward into the bowl. When thelower end of the tube is cio-sed by the water, air will be preventedfrom passing upward to the chamber 62 and to the container 55 andaccordingly, the disinfectant will be retained therein. A cap 66 closesthe upper end of the container in an air tight manner and at the sametime provides for the filling of the container.

As the water leaves the toilet bowl 64, a charge of disinfectant willtherefore, leave the container, the water dropping from the end of thepipe 63 whereby the disinfectant trickles into the bowl.

It will be understood that other modifications may be made in the designand arrangement of the parts without departing from the spirit of theinvention.

What is claimed is:

In a disinfectant device for toilets, a hollow casing, a tab extendingfrom said casing and adapted to be attached to a supporting structure,V

an elongated neck arranged in the lower portion of said casing, athrottle valve mounted for movement into and out of closing relationwith respect to said neck, a chamber arranged in threaded engagementwith said neck, said neck extending approximately half way down intosaid chamber member to form an air lock with the liquid retained in thechamber member whereby the amount of disinfectant available fordischarge is regulated, a tube having its upper end arranged inengagement with said chamber member and its lower end adapted to extendinto a toilet bowl below the normal level of the liquid, a threadednipple mounted on the upper end of said casing,

and a cap arranged in threaded air-tight engagement with said nipple.
